Once an engineer, always an engineer.

I came home from work today and the guy who owns the apartments was outside hanging christmas lights. Above the office door he had shaped the lights into a simple, triangular christmas tree. This tree was perfectly centered, and absolutely symmetrical. I started laughing and he asked me what was so funny. I said, "you must have been an engineer to go to that much trouble to get that tree perfect like that." He laughed and told me he did get his degree in engineering. As I was walking off he said, "Don't tell my wife, but look at this." Then he pulled out some graph paper with the tree sketched on it, along with coordinates.
